Police said Jeffrey Giuliano, an elementary school teacher, confronted a masked intruder near his home around 1 a.m. on Thursday, Sept. 27, only to later realize the masked man was his 15-year-old son Tyler.

Long-time family friend and attorney Gene Zingaro said even with information from Tyler’s computer, the family may never know why their popular, well-adjusted son who was doing well in school lunged at his father with a knife in hand, or why he was apparently trying to break into his aunt’s house.

“We are always going to be speculating as to what he was doing that night,” Zingaro told WCBS 880 Connecticut Bureau Chief Fran Schneidau.

Zingaro earlier this week said the Giulianos are fully cooperating with the investigation.

“I think that state police are going to need to eventually hack into the computer with their computer experts to find out some of these answers,” Zingaro told Schneidau.

Investigators will likely be able to access the teen’s computer by early next week, Zingaro said.

The medical examiner determined Tyler died from multiple gunshot wounds. No charges have been filed in the case.
